Abstract
A photoelectric conversion apparatus includes a plurality of photoelectric conversion units. Each of the plurality of photoelectric conversion units includes a photoelectric conversion element, a first amplification transistor, and a load transistor. Each of a first control unit and a second control unit includes a connection transistor including a gate and a drain connected to the gate, a reference current source and a first switch. The gate of the connection transistor of the first control unit is connected to each gate of the plurality of load transistors corresponding to the plurality of photoelectric conversion elements disposed in a first row. The gate of the connection transistor of the second control unit is connected to each gate of the plurality of load transistors corresponding to the plurality of photoelectric conversion elements disposed in a second row.
